Application filed September 12, 1921.

T 0 all whom it may concern Be it known-that I, HERTHA JOAN NIsLE, acitizen of the United States, and a resident of the city of Chicago, inthe county of Cook and State of Illinois, have invented a new and usefulImprovement in Cradles, of which the following is a full, clear, andexact description.

My invention relates toachilds bed of the type of construction commonlyknown as a cradle, and it consists in the combinations, constructions,and arrangements herein described and claimed.

An object of my invention is to provide a device of the characterdescribed, in which a body or receptacle in which a child may be placedis supported for oscillation, and means are provided for oscillating thebody or receptacle. l

A further object of my invention is to provide a device of the characterdescribed, in which the direction of oscillation of the body may bevaried at will.

A further object of my invention is to provide a device of the characterdescribed, in which the extent of oscillatory movement of the body maybe varied.

A further object of my invention is to provide a device having meanscontrolled by a time recording mechanism for determining theoscillations of the body or receptacle at a predetermined time.

Other objects and advantages will appear in the following specification,and the novel features of the invention will be particularly pointed outin the appended claims.

-My invention is illustrated in the accom panying drawings, forming partof this application, in which- Figure 1 is a side elevation of thedevice,

Figure 2 is an end view, partly in section, of a fragmentary portion ofthe device,

Figure 3 is an enlarged plan view of a fragmentary portion of themechanism shown in Figure 2,

Figure 4 is a detail of another fragmentary portion of the device, and

Figure 5 is a detail of still another fragmentary portion of the device.I

In carrying out my invention, I provide a pair of supporting endmembers, having upright portions 1 equipped with legs 2 and fashionedadjacent to their upper ends to form downwardly inclined portions 3,provided with hemispherical sockets 4. The upright portions 1 areconnected by a hori- Specification of Letters Patent. Patented June 20,1922.

zontal frame member 5, whereby the supporting end members will bemaintained in the position illustrated, when placed on a horizontalsurface, such as the floor 6.

A body or receptacle in which the child is to be placed is indicatedgenerally at 7 and comprises inclined sides 8--8, inclined ends 9-9, anda horizontal bottom 10. The body or. receptacle 7 may vary considerablyin construction from that illustrated in the accompanying drawings,without departing from the spirit and scope of the invention, since itis only essential to my invention that a suitable receptacle adapted toreceive a child be provided, whereby the child will be supported withoutdanger of falling from the receptacle. In the form of the deviceillustrated, the body or receptacle is made up of a frame, to which isattached a foraminous material 11, such as netting or wicker work, toform the sides, ends, and bottom of the body, whereby proper ventilationof the body is assured. However, I do not insist upon this construction.

The ends'99 of the body or receptacle are equipped with eyelet members12-12, which are attached thereto intermediately at their upper edges;These eyelet members are connected with the inclined portions 3 of theend supports by connectors 13--13 and 14 14, whereby the body orreceptacle is suspended for a universal movement with respect to thesupporting'end members. In

the form of the device illustrated, each .connector 14 is fashioned in aball portion 15 at one end working in the socket 4c and maintainedtherein by a retaining ring 18 which has a threaded connection at 17with the socket 4. Each connector 14: is formed with a socket 18 at itslower end adapted to receive a ball portion 19 which is integral withthe connector 13. A retaining ring 20 having a threaded connection at 21with the socket 18 contains the ball member 19 in the socket 18. Theconnector 13. is formed with an. eye 22 at its lower end engaged withthe eyelet 12 at the adjacent end of the body or receptacle 7 The bottom10 of the body or receptacle has secured thereto at its approximatecenter a plate 23 which is fashioned with a depending bracket arm 24fashioned at its extremity into ball form, as at 25. The ball portion ofthe bracket arm is received within a socket 26 of a cross head 27, andis maintained therein between springs 28 and Q 29, the tension of thesprings on the ball portion being adjusted by means of an ad- Justingscrew 30. The latter is disposed in v is rigidly connected to or formedintegrallya hub 32 mounted on a crank a threaded-bore 31' which extendsthrough ,the wall of the cross head and opens into the socket 26, asshown. The cross head 27 and adjustably supported at one end on thehorizontal frame member 5, being fashioned with a slot 39. A pivot pin,which is preferably a bolt capable of manipulation to lock the baseplate 38 at a desired angle to the horizontal frame member 5, is proected through the slot-39 and through the horizontal frame member 5.

The base plate 38 also supports a motor 41 which has a drive shaft 42 onwhich is mounted a relatively small gear 43 in mesh with a relativelylarge gear 44. The latter is mounted on a shaft 45 journalled in abearing 46 superposed on the plate 38. A relatively small gear 47 ismounted on. a

I shaft'and is in mesh with teeth 48 formed on a periphery of thecrankdisk 35. The latter is substantially equal in diameter with theintermediate gear 44, whereby the crank disk 35 will be driven at aspeed considerabl less than that of the drive gear 42.

g housing 49 encases the motor 41 and the gear train just described,being provided with a flange 50 attached to the base plate 38 by bolts51 or like fastening means. The

pitman or connecting rod 31 extends through the opening 52 in thecasing, as

shown.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood. When the motor 41 isactuated in the manner described,'the body or receptacle 7 will beoscillated in a manner simulating the rocking motion im lparted to acradle supported on rockers. heextent of the oscillation 01' the body orreceptacle 7 may be varied at will by positioning the crank pin 33 indifferent openings 34 through the crank. disk.

The direction of oscillation of the body or I receptacle may likewise bevaried at will by swinging the base plate, which'is relatively long,about the axis of the pivot pin 40 to tacle. As a result, the body maybe oscillated longitudinally, laterally,

or obliquely.

The extent of oscillation of the body or receptacle may be furtheradjusted by movthe base plate 38 with respect to the p1vot pm 40 toposition the latter at various positlons alon the slot 39.

It is desirab eto providemeans for actuating the motor 41 automatically,without action on the part of the attendant for the child. With thisobject in view, an electric time recording mechanism 53 is supported onthe end member 1, and is operatively connected as by means of anelectrical conducting wire 54 with an electric switch 55. The timerecording mechanism 53 and the switch 55 are provided with conductors 56and 57 respectively, by means of which they may be connected with themotor operating circuit. The time recordin mechanism 53 and the switch55 are or inary in construction. It will therefore be understood thatthe time recording mechanism 53 may be set to open or close the motoroperating circuit at given times. Consequently, the oscillation of thebod or receptacle 7 may be begun or steppe at given times,

without an actionon' the part of the attendant being required.

I claim:

of oscillation of the receptacle.

' 3. A device of the character edescribed comprising a receptaclesupported for oscillation, a mechanism having a reciprocating pitman,said pitman being arranged to engage said receptacle to oscillate thelatter, and a base for supporting said mechanism,

said base adapted to be moved relative to said receptacle to vary thedirection of oscillation of said receptacle.
